Fig. 4From: Interfractional target changes in brain metastases during 13-fraction stereotactic radiotherapyWaterfall plot of dose differences between the initial GTV and mid-treatment GTV. Diff_midGTVDXX% was defined as {GTVDXX%(mid-treatment) minus GTVDXX%(initial)} × 100. GTVDXX%(mid-treatment) was the radiation dose covering XX% of the mid-treatment GTV in the initial SRT plan, and GTVDXX%(initial) was the radiation dose covering XX% of the initial GTVBack to article page
